Last night earth’s magnetic field was affected by a partial-halo CME launched from Sunspot Region 2473 on Dec. 28th. The early affects were not as strong as expected and resulted in just active geomagnetic conditions. Nevertheless, I had a blast out there at -12°C and a considerable windchill. On one spot coyotes scared me away. But I also witnessed a fairly bright fireball around 11.20pm, this here was on my way back home just outside the Edmonton city limits. The moon was helping to illuminate the scenery. via Tumblr http://bit.ly/1ZFA62h
